Yup, this is not only planned, but I have some wireframes showing exactly how to do it. I'm going to add the follow four buttons to the bottom of every story (but after you scroll ... not at the bottom of the screen):

It would be nice if this dialog wasn't needed. Pocket login details could be configured somewhere else, and the Add confirmation isn't important (because the worst that can happen is I accidentally add a link to my reading list).

After the link has been added, the next dialog says:

Success
Successfully Added!
[Okay]

I don't think this is an important notification that has to be acknowledged. Have a look at how the Twitter iOS app does this - they use a transparent notification with no buttons which times out and dismisses iteself.
